Freelancer profile translated to English.
Back to original languageAbout Alexandre
I build web applications and SaaS products for startups and SMEs — from prototype to production-ready product.
TypeScript fullstack developer with 5 years of experience, I mainly work with founders and product teams who need an autonomous developer, capable of handling front, back, and deployment.
What I do concretely:
→ Build a SaaS MVP from scratch (interface, API, database, deployment)
→ Develop new features on an existing product
→ Create custom back-offices and dashboards
→ Redesign or optimize a web application with performance or maintainability issues
Tech Stack:
Frontend: TypeScript, React, Svelte, Vue, TailwindCSS
Backend: Node.js, Hono, SvelteKit, Next.js, Adonis.js
Database: PostgreSQL
Infra: Docker, Vercel, Railway, CI/CD GitHub Actions
My approach: I work as a member of your team, not as an external contractor. I understand product challenges, make pragmatic technical choices, and deliver clean, maintainable code.
Available for remote work — short or long missions, time & materials or fixed price.
